The present invention relates to an orally available galenics formulation of Valproic Acid or derivatives thereof exhibiting a specific bi-phasic pharmacokinetic profile optimized for maximum inhibition of histone deacetylases in a therapeutic setting. This specific galenics formulation is designed for the treatment of malignant diseases and diseases associated with hypoacetylation of histones or in which induction of hyperacetylation has a beneficial effect, e.g., by induction of differentiation and / or apoptosis. Due to the bi-phasic release pattern the resulting pharmacokinetic profile is able to inhibit HDAC target enzymes most efficiently and to subsequently induce histone hyperacetylation in a rapid as well as a long-lasting fashion. This profile secures the efficient modulation of a desired target gene expression profile which contributes to the therapeutic benefit.

Use of valproic acid for enhancing production of recombinant proteins in mammalian cells

Culturing cells for the commercial production of proteins for diagnosis and therapy is a costly and time consuming process. The equipment required is expensive, and production cost are high. In order to provide commercially viable processes it is desirable to use cell lines which produce large quantities of product with each production run. However, most cells do not produce large quantities of desired product per se either because they do not produce a large quantity of product per unit of time (specific productivity) or because they do not survive long enough in the culture medium (time). Here, we identified that addition of a valproic acid compound to the culture medium increases overall (batch) yield and titer. More importantly, compared to the widely used sodium butyrate, batch yields using a valproic acid compound as a medium additive are significantly higher.
